XL1507-ADJE1

XLSEMI · DC-DC Converters · TO-252-5

XL1507-ADJE1 from XLSEMI, in a TO-252-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Supply Voltage Input Pin. Operates from 4.5V to 40V DC. Bypass VIN to GND with a suitably large capacitor (e.g. 470uF/35V) to eliminate input noise. Absolute max -0.3 to 45V.
2 OUTPUT output Power Switch Output Pin (SW). Switch node that connects to the external inductor and catch (Schottky) diode to supply power to the output. Capable of 3A output current.
3 GND power_in Ground Pin. Care must be taken in layout: this pin should be placed outside the Schottky diode to output-capacitor ground path to prevent switching current spikes from inducing voltage noise into XL1507. The metal tab is also connected to GND.
4 FEEDBACK input Feedback Pin (FB). Through an external resistor divider network, senses the output voltage and regulates it. Internal feedback threshold voltage is 1.23V (typ, min 1.193V, max 1.267V). Absolute max -0.3V to VIN.
5 ON/OFF input Enable Pin. Drive ON/OFF pin LOW to turn the device on; drive HIGH to turn it off. Floating defaults to low (device on). TTL compatible with hysteresis. Absolute max -0.3V to VIN.
TAB GND power_in Metal Tab electrically connected to GND. Provides thermal dissipation path; solder to a ground copper pour to reduce junction-to-ambient thermal resistance (RJA typ 50 C/W without heatsink).
